Answer : Option C
Explanation :
Let Arun's weight by X kg.
According to Varun: 65 <<X < 72
According to Varun's father: 60 < X < 70.
According to Varun's sister: X <= 68
The different possible weights of Varun or the values that satisfy all the above conditions are 66, 67 and 68.
So, the Average of different possible weights of Varun = (66+67+68) / 3
= 201/3
= 67 kg.
